Yuav ua li cas daws Pogo tus pin taub hau dai tin?
Thaum lub sij hawm xeem, Pogo tus pin koob feem ntau tuaj rau hauv kev sib cuag nrog cov khoom siv los yog cov pins, thiab cov tin-hanging mob inevitably tshwm sim. Txoj kev tam sim no los daws qhov teeb meem no tuaj yeem tswj tau zoo los ntawm kev hloov cov khoom siv txheej ntawm rab koob.
Hais txog txheej txheej ntawm Pogo pin koob, feem ntau ntawm cov ntaub ntawv tam sim no siv yog Au cov ntaub ntawv. Lub adhesion ntawm Au rau Sn yog qhov muaj zog heev. Txhawm rau daws qhov teeb meem ntawm cov yam ntxwv ntawm cov khoom siv, cov ntaub ntawv Pdco tuaj yeem siv los hloov Au. Pico kuj yog tib yam. Nws kuj yog ib yam khoom uas muaj nqi heev. Piv nrog kub, nws muaj cov khoom nram qab no.
(1) Hardness
Pico muaj qhov hardness ntawm 450HV
Lub hardness ntawm Au yog 200HV
Qhov tawv tawv ntawm Pdco yog siab dua li ntawm Au, uas ua rau Pdco muaj kev hnav zoo dua li Au
(2) kev sib txhuam
Kev sib txhuam coefficient ntawm Pdco yog .40
Kev sib txhuam coefficient ntawm Au yog .65
Qhov qis coefficient ntawm kev sib txhuam tuaj yeem pab cov koob txav tau yooj yim dua nyob rau hauv lub raj phab ntsa
(3) Particle loj
Pdco loj yog 50-150 Angstroms
Qhov loj me ntawm Au yog 200-250 Angstroms=0.000000000001 meters
Cov khoom me me yog qhov nyuaj rau ua rau oxidation nto
(4) Toughness
Pico: 3-7% elongation
Au:< 3%="">
Lub zog saum npoo toughness Nyob rau hauv kev sib tsoo ntawm rab koob thiab kev sib cuag, qhov saum npoo tsis tshua muaj kev tawg.
Los ntawm cov ntaub ntawv saum toj no, nws tuaj yeem pom tias Pdco zoo dua rau Au ntawm cov khoom siv. Tab sis tag nrho cov ntaub ntawv tsis zoo tag nrho. Qhov tseem ceeb tshaj plaws ntawm kev tiv thaiv yog Au yog siab dua Pico!
(5) Kev ua haujlwm siab (cov ntaub ntawv tau txais nrog tib lub sijhawm ntawm kev siv nyob rau hauv tib rab koob, qhov sib txawv plating xeem ib puag ncig)
Ua 19mΩ
Pico 26 mΩ
Yog tias koj ntsib cov khoom lag luam uas muaj kev nkag siab ntau dua rau cov ntaub ntawv impedance, qhov ntsuas qhov ntsuas ntawm Au yog qis dua li ntawm Pico.
Txhawm rau ua tiav, aiming ntawm cov yam ntxwv ntawm Pdco thiab Au. KITA tau tsim cov txheej txheej tshiab uas ua ke cov khoom ntawm ob cov ntaub ntawv 2-2
Nyob rau hauv cov nqe lus ntawm hluav taws xob tsis kam, cov ntaub ntawv ntawm alloy 2-2 yog heev ze rau cov ntaub ntawv ntawm Au, thiab nyob rau tib lub sij hawm nws muaj peev xwm tau txais tib yam tin-dawb yam ntxwv li Pdco, thiab hardness ntawm cov khoom yog siab tshaj li ntawm. Au thiab Pico.
Qhov sib txawv hardness:
Lub hardness ntawm Alloy2-2 yog 680HV
Pico muaj qhov hardness ntawm 450HV
Lub hardness ntawm Au yog 200HV
Hauv Alloy 2-2, 4 txheej kub yog them raws li cov khoom siv raw kom ua tiav qhov kev ua tau zoo.
Yog li ntawd, cov txheej txheem tshiab 2-2 tuaj yeem siv los txhim kho qhov teeb meem zoo thaum cov qib ntawm cov tin dai yog qhov siab. Yog xav paub ntxiv txog 2-2, thov hu rau tus engineer.
